In a small bowl, combine the sugar and cinnamon. Mix well and set aside.

Roll the pie dough into a large rectangle (approximately 8" x 12").

Brush the top of the dough with the melted butter.

Sprinkle a generous portion of the cinnamon-sugar mixture on top of the dough (don't forget the edges!)

Using a pizza cutter, cut the dough into strips approximately 3/4"-1" wide.

Twist each strip into a spiral and place on a parchment-lined cookie sheet.

Bake at 425° for 8-10 minutes, or until pie dough is golden brown and crispy.

If desired, stir together the powdered sugar and milk until smooth. Drizzle over the cinnamon-sugar twists. Serve warm!
